Are you / your loved one an INTJ? 39 thoughtful descriptions to strategically understand them

A family friend Z who has been very kind to us and shares similar interest in stocks, appears to be an INTJ, I may be wrong, but I am highly interested to understand him, so that we can be a good, supportive friend of him.

Sometimes, I think that he can be an INFJ instead of INTJ because once he said the importance of making decisions by applying person-centered values.

Perhaps, a friend who kindly gave me a shelter in Boston is also an INTJ. Think of Gandalf and Vito Andolini Corleone of The Godfather by Mario Puzo.

@~@ perfectionist : INTJs have exceptionally high standards, and if they view a colleague or supervisor as incompetent or ineffective, respect will be lost instantly and permanently.

@~@ self-confidence that can be mistaken by others as arrogance

@~@ INTJs value personal initiative, determination, insight and dedication, and believe that everyone should complete their work to the highest possible standards
@~@ easily recognize patterns in events and establish thorough explanations
@~@ open-minded yet guarded
@~@ ambitious yet private
@~@ curious and deeply intrigued by all aspects of the human experience, but they do not squander their energy

@~@ pragmatic

@~@ analytical problem-solvers, eager to improve systems and processes with their innovative ideas

@~@ possess the unusual trait combination of imagination and reliability

@~@ INTJs use their creativity and imagination not so much for artistry, but for planning contingencies and courses of action for all possible scenarios.

@~@ the architect / supreme strategists – always scanning available ideas and concepts and weighing them against their current strategy, to plan for every conceivable contingency
@~@ approach reality as they would a giant chess board, always seeking strategies that have a high payoff, and always devising contingency plans in case of error or adversity, constantly outmaneuvering their peers in order to maintain control of a situation while maximizing their freedom to move about.

@~@ values solitude

@~@ natural leaders, although they usually choose to remain in the background until they see a real need to take over the lead.
@~@ has a natural thirst for knowledge and enjoy sharing what they know; their primary interest is not understanding a concept, but rather applying that concept in a useful way.
@~@ simultaneously the most starry-eyed idealists and the bitterest of cynics
@~@ Rules, limitations and traditions are anathema to the INTJ personality type – everything should be open to questioning and reevaluation, and if they see a way, INTJs will often act unilaterally to enact their technically superior, sometimes insensitive, and almost always unorthodox methods and ideas.
@~@ useful to learn to simulate some degree of surface conformism in order to mask their inherent unconventionality; Authority figures do not impress INTJs, nor do social conventions or tradition, and no matter how popular something is, if they have a better idea, INTJs will stand against anyone they have to in a bid to have it changed.
@~@ less comfortable with the unpredictable nature of other people and their emotions.
@~@ INTJs are the most independent of all the sixteen types and take more or less conscious pride in that independence.
@~@ selective about their relationships, preferring to associate with people who they find intellectually stimulating.
@~@ Among types least likely to suffer heart disease and cardiac problems
@~@ Least likely of all the types to believe in a higher spiritual power
@~@ One of two types with highest college GPA
@~@ Among types with highest income
@~@ Personal values include Achievement
@~@ Of all types, least likely to state that they value Home/family, Financial security, Relationships & friendships, and Community service
@~@ Over-represented among MBA students and female small business owners
@~@ Commonly found in scientific or technical fields, computer occupations, and legal professions
@~@ gain the most satisfaction from turning their ideas into reality.
@~@ INTJ will never be comfortable with a truly public display of emotions
@~@ In friendship, INTJs are looking for more of an intellectual soul mate than anything else, and those that aren’t prepared for that kind of relationship are simply boring. INTJs need to share ideas – a self-feeding circle of gossip about mutual friends is no kind of social life for them. INTJ especially like to spend time with other Intuitive Thinkers, and also usually enjoy the company of Intuitive Feelers. These personality types love to theorize and speculate about ideas, and so can usually relate well to the INTJ, who loves to analyze ideas.
@~@ INTJs will keep up with just a few good friends, eschewing larger circles of acquaintances in favor of depth and quality. Having more than just a few friends would compromise INTJs’ sense of independence and self-sufficiency – they gladly give up social validation to ensure this freedom.
@~@ The sarcasm and dark humor of INTJ are not for the faint of heart, nor for those who struggle to read between the lines, but they make for fantastic story-telling among those who can keep up. This more or less limits their pool of friends to fellow Analysts (NT) and Diplomat (NF) types.
@~@ INTJs also recognize that life is often the best teacher, and they will tend to be fairly liberal, allowing their children to have their own adventures and make their own decisions, further developing these critical thinking skills.
@~@ INTJs prefer more "lone wolf" positions as mechanical or software engineers, lawyers or freelance consultants, only accepting competent leadership that helps in these goals
@~@ Efficiency and results are king to INTJs
